“A flock of black birds flew by, screeching loudly. Passing through he clouds, they soared into the distant sky. "Do you know what kind of birds those are?" I asked. "They're a type of cuckoo," Honda said. "In Australia, they're called rainbirds. They're thought to sing before stormy weather--it has something to do with their migration patterns." So those were rainbirds.”
